Yep, it was just me. I am glad I don't appear to have ruined anything important. Got firmware loaded and connected to TunerStudio without a glitch. Thanks again to all and sorry for wasting your time.

It appears I am a complete confused person. I ordered a MS3 and have been trying to load code for a MS2. While the MS3 does come with a V3.0 board and the setup instructions are very similar in the MegaManual, they are also very different and not located on the MegaManual website. Thanks to everyone ...

So I just found http://www.msextra.com/downloads/ and I think I may be not so smart sometimes. Good god, at least I hope so. I'll update later hopefully.

Lance,

Thanks for the reply. I am still getting the error I posted above when I run the MS Downloader. I do have V2.00 and am using the most current code I could find. I have never gotten past the "Erasing main FLASH:" stage as it always errors out. I now have a 9-pin DB9 pass through serial cable ...

The latest s19, 2.920.

If you mean the crystal on the main PCB, it's not needed for MS2. Thing that caused a problem loading code here once was a too low powered PS. Which seemed OK on first test with a Stim. Needs to be at least 500mA. A quick check would be to use a fully charged car battery - but do fit a fuse to the ...

Hi and I would just like to say that I feel your pain as I spent many hours trying to get my laptop to communicate with my MS2 V3.0 ! I even purchased the Trendnet TU-S9 usb to db9 converter cable which is confirmed to work with the MS .

What I eventually did to get the whole thing to work ...

OK, I officially am out of ideas. I have a confirmed pass-through cable connected straight to a 9-pin serial port on my tower. I am still getting the below error:
Detected MS-II (HCS12) code.

This is what I am getting from MS Downloader:

Entry point: 0x0000

That is with a usb to db9 cable ...

I will when I get home, I should have done that last night. Sorry

Unfortunately I did not though my understanding was that if it passed the loopback test then it was good to go. Is that not the case?

Good evening,
I am having trouble getting my bootloader code on my MS-II. I don't have access to true serial port. I have a USB cable that plugs into the MS-II daughter board and a usb to serial that plugs into the DB-9 port. Both pass the loopback test just fine and tunerstudio can see both just ...
